The module provides input voltage for the downstream DC/DC converter when a power failure occurs, such that if the input power returns to normal range within a specific period of time, the downstream DC/DC converter (and therefore the load) can't tell that a power failure had happened. This unit is designed to be used with most of Milpower Source's DC/DC converters and DC/AC inverters (consult factory for applicability to specific models). During normal operation, an inte rnal converter charges the internal capacitors (and external, if connected) to 48 to 52 V. In case the input voltage falls below 16 V, the input is disconnected from the output via an internal MOSFET switch, and the caps are connected to the output pins th rough another internal MOSFET switch. The caps are then naturally discharged into the cascaded power supply, until the caps have been depleted to a level that the voltage is below the cascaded power supply's under-voltage lockout threshold (for Milpower Source's converter this value is usually between 16V to 18V). When input power returns (it can happen during cap discharge or after complete loss of power), the MOSFET switches disconnect the output from the caps, reconnect the input to the output, and the i nternal converter recharges the caps, preparing them for the next power failure.

Signal type is open collector of a PMBT2222 bipolar transistor. FAIL: Condition: Input voltage was within normal range and dropped below 17.6 ± 0.5 V. Result: The pin will be pulled down to INPUT FAIL RTN pin through a 6.2 Ω resistor. NORMAL: Condition: Input voltage returned to above 17.6 ± 0.5 V. Result: The pin will go into high impedance mode (OPEN). If this function is not required, leave this pin unconnected. This signal is referenced to INPUT FAIL RTN (pin 2) SYNC (pin 16) This signal is used to synchronize the internal switching converter's frequency to external clock . Valid external clock frequency is 250 kHz ± 10 kHz; Valid duty cycle: 50 ± 10% When no external clock is present, the power supply uses its internal clock. If this function is not required, leave pin unconnected. This signal is referenced to SYNC RTN (pin 17) EXT CAP (pins 4 and 19) Connect these pins to external capacitor for increased holdup time. Unless specified otherwise in the specific variant's catalog page, the voltage at these pins is set to 51 VDC. These pins are referenced to EXT CAP RTN (pins 3 and 18) . INPUT (pins 8, 9, 10, 23, 24 and 25) Connect these pins to the input power source. These pins are referenced to INPUT RTN (11, 12, 13, 26 and 27) and OUTPUT RTN (pins 14, 15, 28, 29 and 30) OUTPUT (pins 8, 9, 10, 23, 24 and 25) Connect these pins to the downstream Milpower Source DC/DC converter. These pins are referenced to OUTPUT RTN (pins 14, 15, 28, 29 and 30) and INPUT RTN (11, 12, 13, 26 and 27)
